Weird stat about Michigan and Final Fours. Their first ever (1964) they lost. Since then, they have made seven trips. They are 7-0 in Final 4 games, and 1-6 in National Championship games.
So for picking purposes, if you put Michigan in your Final 4, you'd better pick them to win that game, and no more. Picking a FF loss, or an NC win is historically a bad bet.
